SPECIFICATION forming part of Letters Patent No. 399,220, dated March 5 1889.

Application filed uly 23, 1888. Serial No.280fl03. (N modeld To all whom it may concern,-

Be it known that I, RUDOLPH TnnRorH, of Chicago, in the county of Cook and State of Illinois, have invented a new, useful, and

1m proved Portable and Adjustable Fly-Table for Printirig-Presses, of which the following is a full, clear. and exact description, referones being" had to the accompanying drawings, forming a part of this swn-ilication, in

which Figure 1 is a side view of a portion of a printing-press and a front View of my improved table in operative proximity thereto. Fig. 2 a vertical longitudinal sectional view of said table upon the line :1: .r, Fig. l; and Fig. 3 is a sectional view of the same in plan, taken upon the line z y, Fig. 2.

Like letters of reference in the different figures indicate like parts.

The object of my invention is to provide means whereby the top of a pile of sheets as they are delivered by the Ily from a printing-press may be made to maintain substantially the same level as that of the axis of the fly, so that as the sheets accumulate and the pile increases it will not have to be removed from time to time, but may be permitted to remain until a large quantity is obtained, when the whole may be removed with the 0 table or support, thereby saving unnecessary handling and preventing the breakage and injury of the paper resulting therefrom.

To this end my invention consists in the combination of elements hereinafter more particularlydescribed, and definitely pointed out in the claims.

In my improved portable table I employ an ordinary platform hand-truck, in the drawings of which. A represents the platforimwhich is supported by suitable frame-work upon wheels (1. Extending along the respective sides and across the ends, upon the top of said platform, are bars a which are rigidly scoured thereto. Pi voted to the bars a a, at or near the points 4') I), are bars B B, which are pivoted at their middle, Z), to the middle of like bars, C C, in the form of lazytongs. The bars (l (J are pivoted at c, Fig.

2, to cleats (Z, rigidly secured to a table, D, 1 and 2,tl1e opposite end of which is loosely supported upon frictioirrollers Z1 Fig.

2, upon the free ends of. the bars B. Metal plates (1. Fig. 0 are provided to serve as bearings therefor. The lower ends of the bars C O are arranged to rest and slide upon plates o 61?, Figs. 2 and 3, upon the platform A, and are loosely attached to a cross-bar, Ethrough the middle of which is passed a horizontal screw, P, which is mounted in bearings f f. rigidly attached to the platform A, the jour- 6o naLbearings being smaller than the body of the screw, so as to prevent an endwise movement of said screw within the bearings. Upon. the outer on d of the screw F is attached a haml-wheehj, by which the screw may be 65 n'iaui mlated. The turning of the screw in one or another direction serves to raise or lower the table.

The operation oi said device is as follows: The table is first placed sothatits side adjaccn t to and ]')arall( l with the end of a printing-press, G. The hand-wheel j" is then turned until the table 1) raised substantially to a level with the axis of the fly g. The paper I: is then delivered upon the table 7 5 in the usual way. As soon as itbegins to accumulate above thedesired level the handwheel is turned and the talde lowered until it reaches its lowest level, as indicated in dotted lines in Fig. i. The truck, with the 121- bio and paper thereon, is then drawn away and unltmdod, when theoporation may be repeated.

The advantage of said dovi is that fewer trucks are required to do a given amount of work, and a great saving of space is accomplished, while the paper is not injured, as itis when so frequently handled under the old method.

Having thus described my invention, I 0 clai1n 1. An adjustable portable lly table for printing-presses, consisting of ahand-truck,

a lazy-tongs mounted and pivoted thereon, a screw for actuating said lazy-tongs, and a table mounted upon the latter, whereby the table may belowered in proportion the paper is placed thereon by the lly, substantially as shown and described.

1 2. The combination, with a printing-press,

of a table mounted upon lazy-tongs, a truck specification, in the presence of two subscribfor supporting said lazy-tongs, and a screw ing' witnesses, this 14th day of June, 1888. and hand-Wheel for actuntin the same where- T r v by the top of the paper pile? may be n iade to DOLPH FIMROrl 5 conform to the posit-ion of the fly, substaa1- \Vitnesses:

tizilly as shown anddeseribed. D. H. FLETCHER, In testimony whereof I have signed this J. B. HALPENNY.
